"The Brotherhood of the BEAST" on this site is terrific, and without them, I rather hesitate to think I would even consider tackling this one myself.

The SE-6 carbide bur suggestion turns out to be spot on. And the SE-5L6 w/ 6" shank should be fine as well. After an awkward start (with the wrong bur) I ended up with two perforations of the large radius in two plenum runners. Switching to the suggested SE-6 and alternating between sanding and grinding has made things go 100% better. I did end up perforating the short radius on one more runner, but the plenum runners really look nice. The plenum is done, except for Al doing some of his welding magic to patch up the holes and a little re-grinding.

Now that I have the hang of it, its on to the IHs. Is it spring yet???

P.

Hey Paul, wanna do mine next? LOL
